VALVE FOR DEEP-WELL PUMPS.

Specification of Letters Patent.

Patented Oct. 17, 1916.

Application filed September 4, 1915. Serial N 0. 49,047.

To all whom it may concern Be it known that I, JOHN J. BECKER, a citizenof the United States, residing at Los Angeles, in the county of LosAngeles and State of California, have invented a new and usefulImprovement in Valves for Deep-Well Pumps, of which the following is aspecification.v

This invention relates to improvements in valves for deep well pumps andits prime object is to provide a valve that will have a very largepassageway for liquid and thereby prevent the valve from chocking whenthe pump is run at high speed.

The preferred form as illustrated in the drawings consists of .a pumpplunger provided with a valve seat in its upper end and a valve adaptedto seat in the valve seat in said plunger, said valve being providedwith a series of spirally arranged ribs which form spiral water passageswhen the valve is unseated; and my invention consists of the novelfeatures herein shown, described and claimed.

Referring to the drawings: Figure 1 is a longitudinal sectional viewpartly in elevation of a pump cylinder with the plunger in place and thevalve-seated. Fig. 2 is a longitudinal central sectional view showingthe valve unseated and taken upon the line 22 of Fig. 4:- Fig. 3 is across section taken upon the line 33 of Fig. 1 and showing the valve inplan. Fig. 4 is cross section taken upon the line 4-4 of Fig. 2. Fig. 5is a view of the valve in elevation.

Referring to the drawings in detail, 1 designates a portion of a deepwell cylinder. Within the cylinder 1 is a pump plunger 2, which iscylindrical in cross section to conform to the inside of the cylinder 1.The upper end of said plunger is turned down to form a shoulder 3, forthe reception of a cup packing ring l, the lower end of said ringextending under a second shoulder 5. A dividing ring 6 abuts against thelower end of the packing ring 4- and a second cup packing ring 7 extendsaround the outer face of the dividing ring 6 and under the lower edgethereof. A second dividing ring 8 abuts against the lower end of thepacking ring 7 and a third packing ring 9 extends around the outer faceof said dividing ring 8. The lower end of the plunger 2 is exteriorlyscrew threaded at 10 for the reception of an interiorly screw threadedretaining ring 11. The retaining ring 11 abuts against the lower end ofthe packing ring 9 and holds the several packing rings and dividingrings in place.

The wall of the plunger 2 is comparatively thin and extends upwardly adistance above the shoulder 3. A series of radial ribs 12 are formedintegral with the wall and extend inwardly and merge in a verticalsleeve 13. The sleeve 13 extends upwardly a distance above the upper endof the plunger and is connected by a coupling to the operating tube rod15. The sleeve 13 is provided with a bore 16 through which the plungerrod 17 extends to the lower plunger (not shown). A series of serrations18 are formed in the upper end of the plunger 2 and extend alternatelyfrom near the lower edge of each of the ribs 12 to the upper edge of thesucceeding rib.

The valve 19 is provided with a hub 20 bored to fit the sleeve 13 of theplunger 2, said valve being adapted to operate up and down on saidsleeve. A series of spirally arranged segmental ribs 21 are formedaround the boss 20 and extend from the lower end thereof to near theupper end, each rib extending radially from the boss 20 slightly morethan a quarter of the diameter, so that the upper end of one riboverlaps the lower end of the succeeding rib. The valve 19 is slightlyless in diameter than the plunger 2 so that it may operate freely abovethe plunger in the cylinder 1. The under faces 22 of the outer edges ofthe ribs 21 are of the same contour as the upper edges of the serrations18 in the plunger 2, so that when the valve is seated, as shown in Fig.1, water tight joints are formed between these parts. A series of radialslots 23 are formed in the boss 20 and extend from the lower edgethereof and end under the upper ends of the ribs 21. Said slots areadapted to fit over the ribs 12 of the plunger 2 and form guide ways forthe valve 19 when in operation.

When the valve is seated as shown in Fig. 1 the ribs 12 of the plunger 2cut off the passages formed between the spiral ribs 21 of the valve 19.s

Fig. 2 shows the valve in its open position and the spiral waterpassages formed between the ribs of the valve 19 free for the upwardpassage of liquid. The upward movement of the valve 19 is limited by thecoupling 14.

' What I claim and desire to secure by Letters Patentof the UnitedStates, is

1. A pump plunger comprising a body portion having a serrated upper edgeforming a valve seat, a series of radial ribs formed with the bodyportion and extending inwardly and merging in a sleeve, a valve adaptedto seat in the valve seat formed in said plunger and having a hubadapted to operate on said sleeve, means forming spiral Water passagesaround said hub and means for closing said passages when the valve isseated.

2. A pump plunger comprising a body portion having a valve seat in itsupper edge, a series of radial ribs formed with the body portion andextending inwardly and ending in a sleeve, a valve having a hub adaptedto operate on said sleeve, "said valve having a series of spirallyarranged ribs adapted to fit Within the cylinder and seat in said valveseat in the plunger, and slots formed in the hub of said valve for thereception of the plunger ribs, so that when the valve is seated saidribs close the passages formed between the spiral ribs of said valve.

3. A pump plunger comprising a body portion having a series ofserrations formed in its upper end, ribs extending inwardly from thebody portion and merging in a Copies of this patent may be obtained forsleeve, a valve having a hub fitting around said sleeve, guidewaysformed in the hub for the reception of said ribs, a series of spirallyarranged ribs around the hub, the under edges of the outer ends of saidribs being adapted to seat in the serrations formed in the upper end ofthe plunger and form tight joints, said ribs alternating from bottom totop of the hub and overlapping, so that when the valve is seated theribs formed in the plunger close the passages around the said valve.

4. A pump plunger comprising a body portion having a serrated upper edgeforming a valve seat, a series of radial ribs formed with the bodyportion and extending inwardly and merging in a sleeve, a valve adaptedto seat in the valve seat formed in said plunger and having a hubadapted to operate on said sleeve means forming spiral water passagesaround said hub, means for closing said passages when the valve isseated and a stop formed upon the plunger sleeve to limit the upwardmovement of the valve.
